Glass jacks for doors, windows, walls, etc.

Abstract

A glass jack for doors, windows, walls, etc. having a rectangular frame formed with interconnected stiles and rails providing one or more rectangular openings for receiving a panel, which is mounted in the opening with an outer peripheral edge closely facing adjacent wall surfaces of the surrounding frame members. One or more glass jacks is mounted to extend between the edge of the panel and an adjacent facing wall surface of the frame members at selected point(s) for maintaining an adjustably selected spacing interval between the edge of the panel and the frame member. The glass jack includes an elongated, shank threaded into an opening in the facing wall of the frame member and a radial head having an outer edge surface with ribs and grooves thereon to facilitate manual rotation when adjusting the jacks to control the spacing interval. An outer end surface of the head is positioned to engage the edge of the panel and the end surface is formed with a small deformable annular rib coaxially aligned with respect to the shank. When the jack is tightened the rib is forced against the edge of the glass panel and is deformed in segments provide a stop at engaging corners of opposite faces of the glass panel. The stops formed at the ends of the depressed rib segments resist inadvertent rotation of the glass jacks after a selecting spacing or clearance is attained and a flat portion of the head surface extending between the depressed rib segments bears directly against the edge of the glass.
